Abstract
PURPOSE: To improve weldability and perform correct control of welding arc by adding a short arc discriminating circuit to an output control device of electric power source of a consumable electrode type arc welding and thereby lowering the power output when short circuit and raising when arcing.
CONSTITUTION: Momentary current IA flows at the moment of arc generation and approaches gradually to the reference control winding current IO that determines average welding output. Current IS flows at the moment of short circuit and approaches gradually to the current IO. When control winding current ico are IA, IO, IS respectively, points of magnetic characteristic become PA, PO, PS. Magnetizing force at the time of PA, PO, PS become HA, HO, HS and magnetic flux density become BA, BO, BS. The point of magnetizing characteristic at which the welding power output is the greatest is the point PA, followed by the point PO and smallest at the point PS. Welding arc is controlled by changing IA, IS according to average welding output, especially to average welding current iD.
